Abnormal condition wherein damaged or diseased heart muscle within a ventricle begins contracting on its own, which it normally does not do.
a fast heart rhythm caused by abnormal electrical impulses or circuit within the ventricles
ventricular tachycardia: rapid heart beating that arises in the ventricles of the heart; symptoms include palpitations, rapid heart action, dizziness, lightheadedness, fainting or near fainting; can be treated with medications or by an implantable cardioverter/defibrillator.
This is an abnormal, and potentially life threatening rythm, when the ventricles of the heart have exceeded the rate of the SA node, and are no longer under control of the SA node as well.
A rapid heart beat that originates in the lower chambers of the heart.
Abnormal heart beat in the lower chambers of the heart, usually to a rate of 150-200 beats per minute; may result in fainting, low blood pressure, shock, or even sudden death; common and often lethal complication of heart attack.
a condition in which the ventricles cause a very fast heartbeat.
is an abnormal heart rhythm that is rapid, regular and originates from an area of the ventricle, the lower chamber of the heart. Ventricular tachycardia is most commonly associated with heart attacks or scarring of the heart muscle from previous heart attacks and are life threatening.
a condition in which the ventricles beat very fast.
An abnormally rapid heart rhythm that originates from a ventricle , one of the lower chambers of the heart. Although the beat is regular, ventricular tachycardia is life-threatening because it can lead to a dreaded condition, ventricular fibrillation . See the entire definition of Ventricular tachycardia
A type of arrhythmia that affects the lower chambers of the heart and causes a dangerous and abnormally fast heart rate. If left untreated, it can cause palpitations, fainting, and death.
A series of arrythmogenic foci in the ventricles (usually the left) causing an elevated heart-rate. VT is difficult to map and ablate.
an arrhythmia (abnormal heartbeat) in the ventricle characterized by a very fast heartbeat.
An abnormal heart rhythm (or arrhythmia) characterized by three or more beats of ventricular origin in succession at a rate of more than 100 beats per minute. Ventricular tachycardia may be well tolerated or life-threatening (pulseless).
A heart rhythm disturbance in the ventricle that is characterized by a very fast heartbeat. In most cases, the ventricles are not able to pump adequate blood to the body.
Excessively rapid heart beat due to uncontrolled ectopic focus in the ventricle.
A heart rhythm disorder that originates in the lower chambers. VT is characterized by a rapid heart rhythm during which patients may feel faint or dizzy, or even collapse. During VT, the heart does not pump blood as efficiently as it does during a normal rhythm, and rapid contractions prevent it from filling adequately with blood between beats. VT can be dangerous, life-threatening, if not properly treated. More about VT .
Ventricular tachycardia (V-tach or VT) is a fast rhythm that originates in one of the ventricles of the heart. This is a potentially life-threatening arrhythmia because it may lead to ventricular fibrillation and sudden death.
